（４）も同一の構成である。By the way, the conventional stepping motor has a structure as shown in FIG. In FIG. 3, (1) and (2) are intermediate yokes, (3) and (4) are end face yokes, and (1a) (2a) (3).
a) (4a) is the pole tooth of each yoke, (5) is the stator winding,
(6) is a protrusion for positioning the intermediate yoke, (7) is a notch for positioning the end yoke, (11) is a rotor arranged in the central space of the stator, and (12) is a rotor shaft. Next, the intermediate yoke (1) of the stepping motor having such a configuration.
Positioning means for (2) and the end face yokes (3), (4) will be further described with reference to FIGS. 4 to 6. In the intermediate yoke (1) shown in FIGS. 4 and 5, the central axis y-y and the adjacent pole teeth (1a-1), (1a-2) are θ 1 , θ 2 respectively.
Where θ 1 and θ 2 are the step angles of the motor, where θ 0 and n are integers, θ 1 + θ 2 = 4nθ 0 (1) θ 1 −θ 2 = ± θ 0 is a value that satisfies the expression (2). A protrusion (8) and a hole or a recess (9) into which the protrusion (8) is fitted are formed at symmetrical positions with respect to the central axis y-y. Also, the central axis y
-Protrusions (6a) on the y line and symmetrically around this line
(6b) and (6c) are provided. The intermediate yoke (2) having the same configuration as the intermediate yoke (1) having the above configuration is superposed on the plane (1b) including the projection (8) and the hole (9) to form a part of the magnetic circuit, and then the projection ( 8) and the hole (9) are fitted to each other to position the intermediate yokes (1) and (2). The end face yoke (3) is, as shown in FIG.
It has a pole tooth (3a) and a rising outer peripheral wall (3b). The rising peripheral wall (3b) constitutes a magnetic circuit together with the intermediate yoke and houses the stator winding (5), and the edges thereof have protrusions (6a) (6b) (6) of the intermediate yoke (1).
Notches (7a) (7b) (7c) for engaging with c) and positioning with the intermediate yoke are provided. The end face yoke (4) has the same structure.

である。この様に従来構造のものは180°ずれても中間
ヨークに端面ヨークを嵌合し得るため組立てミスを生じ
る惧れが多分にあつたのである。In the stepping motor having such a configuration, the combination of the intermediate yokes (1) and (2) and the end face yokes (3) and (4) is all based on the fitting of the projection and the hole, the recess or the notch, and the structure of the parts. Since it is determined by the above, and it does not need to depend on a jig and tool, it is excellent in accuracy and assembling efficiency. However, in the conventional structure, the protrusions (6) of the intermediate yokes (1) and (2) and the end face yokes (3) and (4) are used.
Of the intermediate yoke (1) because the notches (7) have the same width dimension and the protrusion (6) and the axis of symmetry of the notches (7) are present at the positions satisfying the expressions (1) and (2). )
Even if the positional relationship between (2) and the end face yokes (3) and (4) is shifted by 180 °, they can be fitted. This is because there is a lead wire lead-out portion (10a) on the opposite side of the protrusion (6a) located on the central axis yy of the intermediate yoke, and a corresponding notch (10b) is provided on the end face yoke side. This is because the protrusion (6a) can fit into the notch (10b) when it is offset by 198 °. As described above, in the conventional structure, since the end face yoke can be fitted to the intermediate yoke even if it is displaced by 180 °, there is a possibility that an assembly error may occur.

いた。Further, when welding and fixing at the fitting position of the protrusion (6) and the notch (7) shown in FIG. 3, it is necessary to simultaneously fix a total of four parts including two end face yokes and two intermediate yokes, which is difficult. Therefore, in the past, a method of welding on the contact lines of the end face yokes (3) and (4) shown in FIG. 3 has been used for assembling and fixing the motor. In this case, the intermediate yoke (1),
(2) is fixed only by the combination, and it is difficult to obtain perfect fixation such as welding. Therefore, when it is used for a large vibration application such as an automobile, this intermediate yoke moves due to the vibration, which causes a trouble. Had a problem.

The same components as those described in the conventional example of FIGS. 4 to 6 are designated by the same reference numerals, and the description thereof is incorporated. In the present invention, as shown in FIG.
The width of one or more of the positioning protrusions (16a) (16b) (16c) of the end face yoke (3) of the intermediate yoke (1) is changed. The protrusions (16b) and the protrusions (16c) at the symmetrical positions have different widths T 1 and T 2 and the notches (17b) of the end face yoke (3) with which the protrusions (16b) (16c) engage. ) (17c) is also set according to this width. In this way, the positioning protrusions (16a) (1
6b) (16c) and the corresponding notches prevent misalignment of the intermediate yoke (1) and the end face yoke (3) by 180 °, as these protrusions and notches cannot be fitted. To be done. It should be noted that by selecting the central axis y-y, when one of the intermediate yokes is reversed by this central axis and one projection (9) and the other hole (8) are fitted back to back, It is known that the pole teeth are offset from each other by θ 0 . Therefore, with this central axis y-y as the axis of symmetry, protrusions (16c) and (16a) are provided at one place if the central axis y-y is located on the center axis y-y and at two locations if not located on the central axis y-y. , (16b) and the end face yoke is provided with a notch corresponding thereto, the intermediate yoke 2 which is completely the same.
It is possible to configure a stepping motor by using one unit and two end face yokes. At this time, the protrusions (16c), (16
Since a) and (16b) are provided on the central axis y-y or at a position with this as the axis of symmetry, when the intermediate yokes are fitted back to back, they are at the same position as shown in FIG. 16b, 16c). This is to prevent the dimensional utilization factor from being deteriorated due to unevenly arranged protrusions and notches on the outer peripheral portion.
これによってより小型のモータも同様に構成することが
可能となる。This allows a smaller motor to be similarly configured.
また、第１図に示す如く、ずれｔが同一部分に来るた

得る。In addition, in the electric motor configured as described above, FIG.
As shown in the figure, when the widths of the protrusions (16b) and (16c) at symmetrical positions with respect to the central axis yy are different, the width T 2 of the protrusion (16c) is changed to the width T of the protrusion (16b). When t is set to 1 and t is increased, t is increased to one side, and the notch of the end face yoke (3) is also formed to match this, and when the motor is assembled, as shown in FIG. York (1)
(2) Positioning projections (16b) and (16) that are adjacent to each other
There is a gap (t) between c). When assembling the motor, the intermediate yokes (1) and (2) can be fixed together with the end face yokes (3) and (4) at once by welding at the gap (t). That is, as shown in FIG. 1, the positioning protrusion of the intermediate yoke (2) has a width of T 2 (16
When it is c), if welding is performed at this gap (t),
The intermediate yoke (2) can be fixed at once together with the end yokes (3) (4). Further, in the notch portion of the end face yoke (not shown in FIG. 1), the positioning protrusion of the intermediate yoke (1) becomes the protrusion (16c) having the width T 2 , so that the intermediate yoke (1) is moved to the end face yoke (3 ) (4) and can be fixed at once.
